nissan leaf emergency charger:A Host of Expensive Issues
As these ultrafast chargers come online, public-charging providers (and automakers) will be faced with new issues. Beyond higher initial costs, these chargers can cost a lot to operate because of surcharges known as demand charges, which are levied by public utilities for energy draws beyond typically expected levels. According to EVgo, these demand fees make up about 80 percent of the operating costs for their chargers.
Installing more stalls per site is one way to smooth out usage, bringing the demand-driven expenses down. 2016 Nissan Leaf at DC fast charger Another issue is that—as programs such as Nissan’s No Charge to Charge have illustrated—users tend to opt for the fastest charger their vehicle can use, whether they need that faster rate or not. The Bolt EV’s predecessor, the Chevrolet Spark EV, saw about 80 percent of units sold with optional fast charging.
Despite the Bolt’s mammoth improvement in range (238 miles versus the Spark’s 82, per the EPA), GM expects at least that same 80 percent will opt for fast charging on the Bolt EV. Automakers are quick to point out that ultrafast charging won’t come cheaply; it involves additional weight in the cars (for batteries and cooling systems) and research and durability testing to make sure battery packs can take it.
Nevertheless, the newest fast-charging hardware paves the way for a handful of vehicles that will be able to make use of it. These include the Porsche Mission E, the Audi e-tron, and perhaps the Lucid Air and the Faraday Future FF91, that will start arriving in 2018 and 2019.
